TOOL-HANDLE.

SPECIFICATION forming part of Letters Patent No. 427,460, dated May 6,1890..

Application filed November 5, 1889- Serial N0. $29,234:. (No model.)

To aZZ whom it may concern:

Be it known that I, FELIX CHANTRELL, a citizen of the United States,residing at Reading, in the county of Berks, State of Pennsyl- Vania,have invented certain'Improvements in Tool-Handles, of which thefollowing is a specification.

The object of my invention is to provide an improved means of quicklyand positively to securing removable bits or tools to the stock orhandle. To accomplish this in the most simple and effective. manner Iavoid entirely the use of screw-threads and springs, the principal of myinvention consisting in clam ping the tool-shank in the hollow stock, bymeans of a jaw and a clamping-sleeve, in such manner that a slightrotary movement of said sleeve will hold or release the tool.

The invention is fully set forth herein in connection with theaccompanying drawings,

and is specifically-pointed out in the claims. Figure 1 is a fullelevation showing my tool-stock adapted to a hollow handle containing avariety of tools intended to be se- Fig.2 is a sectional view through XYof Fig. 1. Fig. 3 shows a modification of my invention.

D represents the handle and C the tool, the shank of which enters thehollow stock B. 0 The latter is formed with a longitudinal slot B withinwhich is fitted a jaw E, pivoted thereto at one end B, so as to permitof its being swung outward, as shown in Fig. 2, or to be closed againstthe tool-shank, in which 3 5 latter position it is about flush withtheouter surface of the stock 13. The sleeve A, when fitted on the latter,is adapted to thus close the jaw against the tool, but is formed with acorresponding longitudinal slot A, which, when brought to coincide withthe jaw E, permits the latter to be moved away from the tool so that itmay be released without removing the sleeve. A pin 15 projects from thestock B and serves to stop the rotation of 4 5 the sleeve at the properpoint to permit the release of the tool. It is preferably made totraverse a circular slot A in the sleeve, thus preventing the withdrawalof the latter except when turned to a certain point.

The shank of the tool C is represented in .50 Figs. 1 and 2 with aprojection or hook C, which enters a recess B in the stock, and isadapted to take the end thrust and torsional strain upon the tool and toprevent the possibility of longitudinal movement when the bit is clampedin place. As shown in Fig. 1, the sleeve is against the stop B and is inposition to permit the jaw E to be swung back to admit or withdraw thetool. A slight rotary motion of the sleeve, however, will very 6oeffectually clamp it.

The modified construction illustrated in Fig. 3 shows the tool formedwith a recess or slot C instead of the projection or hook C, the freeend of the jaw E having a heel E, which engages the recess 0 thusaccomplishing the same purpose.

I am aware that a screw-thimble having a pivoted jaw operated by thepoint of the stock upon which it screws has been employed, also that itis common to form tools with projections to prevent longitudinalmovement.

The features of my invention have been fully set forth, but I do notlimit it to the exact constructions shown, as it may be further modifiedwithout departing from the spirit of my invention.

It will be noticed that no force need be exerted upon the sleeve toeifeetively clamp the toolsuch as is required when a screw-sleeve isemployed and a very slight rotary movement of the sleeve is suificientto prevent the opening of the jaw and to positively hold the tool. Thestrain upon the latter is not conveyed to the sleeve, but is taken bythe stock direct.

WVhat I claim is 1. In a tool-handle, the combination, with a stationarystock having a recessed side, and a movable jaw fitting within therecess, of a rotary clamping-sleeve mounted on the stock and providedwith a slot adapted to register with the movable jaw and permit thelatter to fall back into the slot, whereby the sleeve is locked againstrotation, substantially as set forth.

2. In a tool-handle, the combination, with a stock having a cavity forthe tool-shank, a recessed side and a movable jaw, the latter beingconnected to the stock at a point be low the bottom of the tool-shankcavity, of a rotary sleeve mounted on the stock and provided with a slotadapted, when opposite the movable jaw, to permit the latter to fallback in to the slot, whereby the sleeve is locked against rotation,substantially as set forth.

3. In a tool-handle, the combination, with a stock having a cavity forthe tool-shank, and a recessed side and a movable jaw fitting withinsaid recess, of arotary sleeve mounted on the stock and provided with aslot adapted, when opposite the movable jaw, to permit the latter tofall back into the slot, whereby the sleeve is locked against rotation,and also provided with a slot A and a pin or stop secured to the stockand resting within slot A substantially as set forth.

4. The tool-stock provided with pivoted jaw E, and having a socket withrecess B, in combination with a tool having a projection entered in saidrecess, and a rotating sleeve with longitudinal slot adapted to clampsaid jaw against the tool or release the same, all substantially as setforth.

In testimony whereof I affiX my signature in presence of two witnesses.

FELIX OHANTRELL.
